Impulse Steam Turbine Vs Reaction Steam Turbine
| Parameters | Impulse Turbine | Reaction Turbine |
| Efficiency | For the same flow rate & operating condition, the efficiency of an impulse turbine is very low | For the same flow rate & operating condition, the efficiency of the reaction turbine is high |
| Space Requirement | The size of an impulse turbine is very less. | The footprint required for reaction turbine is high |
| Cost | The Cost of an impulse turbine is much lower when compared to the reaction turbine for the same power rating. | Reaction turbine cost is much higher due to the critical shape of the rotor |
| Application | Widely used in petrochemical and refineries. | Widely used in Power plants. |
| Staging | In the case of multistage impulse turbine, three types of compounding in impulse turbine. They are1. Pressure Compounding
2. Velocity Compounding 3. Pressure – Velocity Compounding
|
No compounding is available |
| Maintenance | Easy Maintenance | Not so easy when compared with impulse turbine |
